C'mon, what possible good does any international agreement brokered by the UN do? It doesn't help us, it won't mandate change in the second and third world, there's no real sustaining money attached, nothing comes of it. There is no rational reason to tie ourselves to the UN. If you think our presence in and endorsement of an agreement makes any difference I believe you may want to think again. We only get our options limited by dalliance with the UN.
